an internal 20k ? (typ) pull-up resistor.
It can be driven from a TTL- or CMOS-
logic line, or shorted to ground with a
switch. Leave open or connect to V CC

MAX6711/MAX6712 have a push-pull output stage.
Connect a pull-up resistor on the MAX6713’s RESET
output to any supply between 0 and 6V.
Manual Reset Input
Many μP-based systems require manual reset capabili-
ty, allowing the operator, a test technician, or external
logic circuitry to initiate a reset. Reset remains asserted

while MR is low, and for at least 140ms after MR returns
high. This input has an internal 20k ? pullup resistor, so
it can be left open if it is not used. MR can be driven
with TTL- or CMOS-logic levels, or with open-drain/col-
lector outputs. To create a manual reset function, con-
nect a normally open momentary switch from MR to
ground; external debounce circuitry is not required. If

MR is driven from long cables or if the device is used in
a noisy environment, connecting a 0.1μF capacitor from
MR to ground provides additional noise immunity.

Detailed Description
Reset Output
A microprocessor’s (μP’s) reset input starts the μP in a
known state. The MAX6711/MAX6712/MAX6713 assert
reset to prevent code-execution errors during power-
up, power-down, or brownout conditions. They assert a
reset signal whenever the V CC supply voltage declines
below a preset threshold, keeping it asserted for at
MAX6712/MAX6713 are relatively immune to short-dura-
tion negative-going V CC transients (glitches).
Figure 1 shows typical transient duration vs. reset com-
parator overdrive, for which the MAX6711/MAX6712/
MAX6713 do not generate a reset pulse. The graph was
generated using a negative-going pulse applied to V CC ,
starting 0.5V above the actual reset threshold and end-
ing below it by the magnitude indicated (reset compara-
tor overdrive). The graph indicates the maximum pulse
width a negative-going V CC transient can have without
causing a reset pulse. As the magnitude of the transient
increases (goes farther below the reset threshold), the
